- Energy rating (cooling)
- 3.5
- Heating: 2
- Annual electricity use
- 3,690 kWh
- 435 cooling + 3,255 heating
- Estimated running cost
- $1,218 / year
- $101 / month · $12,177 over 10 years
- Capacity
- 8.5 kW cooling
- 9 kW heating
2% more electricity than the median of 120 comparable 8 kW reverse cycle split system registrations (3,622 kWh a year) in the cold zone. Uses less than 40% of them.
Across all 3,611 air conditioner registrations sold in Australia, it uses less than 50% (this compares very different sizes, so the cohort figure above is the useful one).
Annual kWh is the government label figure for a residential user in the cold zone (Canberra climate: Canberra, Hobart, Ballarat, alpine areas). All of New Zealand is the cold zone on the Zoned Energy Rating Label. Cost = kWh × 33c/kWh in NZD; change the price above to your tariff.
